Thank you for your reply.
Your understanding is correct.
Provided you remain non resident in the UK for UK tax purposes in this tax year 2016-17, any gains made on sale of unit trusts and financial investmenst would not be chargeable to UK CGT.
I hope this is helpful and answers your question.
If you have any other questions, please ask me before you rate my service – I’ll be happy to respond.
You would have stayed outside the UK for at least 5 full tax years ..come back on 6 Apr 2017 and not 5 Apr 2017.
You don't have to declare these gains in your 2016-17 tax return as you would be non-resident for tax purposes.
I hope this is helpful.
